Thisinvention relates to improvements in loading machines and has reference more lparticularly to an improved machine for andling coal and for the handling and loading of muck at mines and for similar purposes. f

In coal and metal mines and wherever material is broken down b means of explosives, the broken coal or muc must be loaded onto cars so as to be removed. Where there is sufcient head room such loading may be accomplished by lmeans of mechanical shovels, of the type referred to as steam shovels. AIn coal mines, and in many other places, there is not suilicient head room for operating a steam shovel of the ordinary construct-ion and resort must, therefore, be had to some different typesof machines or else the loadin must be effected by manual labor.

t is the object of this invention to produce a loading machine that shall be very low and which can, therefore, be operated in mines having very limited head room. It is the further object of this invention to produce a loading machine of a. simple and substantial construction'that can be easily constructed and which will be very effective in handling coal and other materials that are broken up into comparatively small pieces.

In order to properly describe this invention, reference willvnow be had to the accompanying drawings in which one embodiment thereof has been illustrated, and in which:

Fig. 1 is a side elevation of my improved loading machine showing the lsame in use for transferring material from a muck pile to a car;

Fig. 2 is a section taken on line 2-2, Fi 0. 1

Fig. 3 is a section taken on line 3-3, ig. 2; and

F'g. 4 is a section taken on line 4 1, Fig. 3

Numeral 1 indicates the side members of the supporting frame, these have been shown as being formed from angle irons. This frame is supported by means of two spaced wheels, 2, 2 located on each side of the frame.

In the form illustrated, these supportingl wheels are of the ordinary car type wheels, which are adapted to run on the track rails 3. I have not shown the supporting frame in detail as this is merely conventional and can be made in an suitable way. This specification will there ore be directed more particularly to the structure of the mechanism employed in removing the muck from the pile and transferring it to the, loading conveyor.

Supported from the front ends of the side members 1 are two spaced U-frames 4, which have vertical side members 5 connected by a transverse'top .member 5'L (Fig. 2.). These U-shaped frame members are secured to the side frame pieces 1 by means of brackets 6 and bolts 7 and 8. These brackets are each provided with a pair of inwardly extending ears 9 between which the grooved pulleys 10 are mounted and to which they are pivotally connected by means of the pivot pins 11. A similar bracket is secured to the under side of the transverse frame member 5a. Supported on the lower pulleys 10 and held from upward movement by the corresponding pulleys secured to member 5 is a. cylindrical casing 12 which is provided on its outer surface with spaced rings 13 that form tracks which cooperate with the 4grooved pulley 10, so as to guide the cylindrical casing and permit it to be rotated about its axis. A ring 4gear 14 is secured to the outside of the cylindrical casing and this cooperates with a pinion 15 carried on the shaft 16. This shaft is mounted for rotation in suitable bearings, one of which has been indicated by numeral 17 in Fig. 1. Shaft 16 extends to and is connected with the drive shaft of an internal combustion engine 18, which is supported on the side bars l. When the engine operates to rotate shaft 16, the casing or drum will be rotated in the direction indicated by the arrow in Fig. 2. Secured to the inner surface of the cylindrical drum are a'plurality of 'shovels 19. These shovels are formed from sheet steel and have two angularly sides, one I i .of which has been indicated by reference numeral 20, and which is curved so as to conform to the curvature of the inner surface of the drum. The other side has been indicated by numeral 21 and is preferably radial with lrespect to the drum. These shovels are secured to -the drum in such a manner that they form parts of spirals and project outwardly `beyond the end of the drum in the direction in which the drum rotates. That portion of the shovels which is located within the drum is covered by means of asheet metal cover 22, which is secured along one edge to the inner edge of the radial side 21 and has its other edge secured to the drum at 23. If we now assume that the drum is rotated in such a direction that the ends of the shovels will move in circles in the direction in which they .which the endless belt 31 extends.

are pointing and if we further assume that the shovels are forced against the side of a muck pile, it will be apparent that the shovels will remove muck which will roll downwardvly into the enclosed space within the covers Fig. 3 it will be observed that the casings 22 are curved in such a wa that .any material contained in them will have a` tendency'to flow downwardlyonto the upper surface of' part 25. ,From the above description it will be apparent that the rotating drum, together with its shovels, 'serves when rotated in the proper direction, to remove material from the muck heap and to elevate the same a short distance and deposit it on the .inclined plate 25.

For the purpose of transferring material to a car, such as that indicated by numeral 27, in Fig. 1, a conveyor 28 has been provided. This conveyor is of ordinary construction and is provided at its upper and lower ends with shafts 29 which carry pulleys 30 about l The outerL surface of this belt is provided with transverse cleats 32 which keep the material from sliding downwardly. During operation this conveyor belt is operatedso that the uppersurface is moved upwardly and therefore the material that is deposited-on the belt will be carried along to the top of the conveyor and deposited in the chute 33 from which it will pass into the body of the car.

l It will be apparent from the above description that b means of my simple apparatus,v

I have u'oed a machine of simple and economica construction that can be used in mines or other places where material is to be loaded onto trucks or onto cars and which will effect a large saving in the cost of handling such materials.

I desire to call lparticularattention to the operati mechanism comprising the cylinder orv rum 12 with its spirally arranged shovels which serve both to gather the material and to elevate the same a short distance and then de osit it in the conveyor.1 One feature of t e machine above described to which attention is directed is, that the parts are ver low so that it can operate in places where iglier machines would be impracticable.

Having described the invention what is claimed as new is:

1. An apparatus of the class described,

comprising, in combination, a supporti frame work a cylinder rotatably supper thereon, a plurality of spiral shovels secured to the inner surface of said cylinderand projecting'from one end thereof, that ortion of the shovels within the cylinder ing en closed, a shield covering a portion of the lower end of the cylinder opposite from the end where the shovels project and means for rotating said cylinder. 2. An apparatus of the class described, comprising, in combination, a sup orting framework, a pair of frames arranged) transversely of said framework, a lurality of grooved pulleys secured to said tliames, a cylindrical member provided with circular tracks supported by said pulleys, a plurality of shovels secured to the inner surface of said cylinder, said shovels extending spirally and projecting from one end of the cylinder, means for closing a portion of the other end of said cylinder and means for rotating the cylinder.

3. An apparatus of the class describedf comprising, in combination, a supporting framework, a pair of spaced parallel U shaped members supported by said framework and each lying 1n a plane at right angles to the axis of t e framework, a plurality of grooved pulleys rotatably secured to each transverse frame, a cylinder supported by said pulleys, said cylinder having a gear rin ,BENJAMIN C.
